I'm not sure what you mean here.  Getting rid of the warning entirely
doesn't seem appropriate.  Skipping the warning if the symbol is
undefined seems plausible.

But note that the symbol type does matter even for an undefined
symbol, as it affects the type of dynamic relocation which will be
generated in adjust_dynamic_symbol().
